Solar Star is a 579-megawatt (MWAC) photovoltaic power station near Rosamond, California. When completed in June 2015, it was the world's largest solar farm in terms of installed capacity, using 1.7 million solar panels, made by SunPower and spread over 13 square kilometers (3,200 acres).
Comparison to similar plants
Compared to other photovoltaic plants of similar size, Solar Star uses a smaller number (1.7 million) of large form-factor, high-wattage modules, mounted on single axis trackers. In contrast, the Desert Sunlight Solar Farm and the Topaz Solar Farm (550 MW each) use a larger number (roughly 9 million) of smaller form-factor, lower wattage thin film CdTe photovoltaic modules on fixed-tilt arrays, rather than crystalline silicon technology, spread over a larger area (about 25 square kilometers). Both approaches appear commercially viable.
There are a number of other solar photovoltaic plants nearby:
- Antelope Valley Solar Ranch (266 MW from 3.8 million thin film panels)
- Alpine Solar (66 MW AC, thin film panels)
- Catalina Solar Project (60 MW, thin film panels)
